[Q] Data connection problem after rooting - G3 Q&A, Help & Troubleshooting

Like the title says,
I'm not sure if its my telco that is causing this problem or my device.
it loses connections and says 'service disabled' for like 1 second and then it reconnects by itself.
I'm really new to rooting and modding as i just moved from an iphone to an android device this year for less than a month ago, but i've done researches before i rooted my phone.
Is this problem caused by rooting my phone or my telco?
Considering that i live on the 26th floor of the apartment and connection is really weak (i get about 1 to 3 bars of connection which is normal)
and i've never really encountered this problem before rooting my phone.

Root would not cause the problem.
Have you flashed some custom ROM?

i might have i'm not really sure. is there a way to check if i've flashed a custom ROM?
i tried to flash CM12 earlier on but instead i accidentally flashed something else instead. but i dont see any changes in my phone other than the connection problem
I'm still picking up on this modding and rooting stuffs for android, so if i appear to be such a noob i'm sorry

Which ROM would you like?
What phone variant you have?
You can download some ROM and flash it through recovery.
Download it from here, but make sure it is for your variant.

I think i've installed a ROM that is causing my data connection problem.
Am i able to go back to stock?
EDIT: Alright i've solved my problem. Althought i couldnt find which file/ROM was affecting my data connection so i decided to do the hard way. Which is unroot my phone and then root it again.

So its fine now?

my desire died out of nowhere... :( please help!, rooted with R5, MCR 3.1 for 2weeks

dear all,
My Telstra branded HTC Desire 8183 died out of nowhere.
Here's what I did:
Rooted with R5
MCR 3.1 ROM (custom kitchen with A2SD+) and r17 froyo rom (mostly MCR3.1)
everything went well, and i was happy with it for 2 weeks (blasting fast HSDPA speed and runs perfectly fine)
i noticed the signal strength was really low two days ago, i thought it was my area having service outage. (called and confirmed) I had my girlfriend's Nexus One AT&T version side by side she's getting full bars.
now the phone will show Emergency Call Only all the time, sometimes even with signal, i wont be able to use the data connection (it's show H, but cant even load google.com with the browser)
Diagnostics that i had done:
unroot with generic WWE rom with goldcard (since the telstra rom that people posted on here have 0.75 bootloader and mine is 0.8 so i can only use 1.21 generic WWE rom)
root again with R5 method
update radio
install MCR 3.1 again
replaced my sim card at AT&T store just to make sure
called AT&T to inquire about service outage
none of them works, now i'm stuck with a phone that doesnt make phone calls and data connection.
did i do anything wrong that mess up the radio of the phone? are these rooting guide and custom rom don't support 8183?
please help me! i really like this phone and it's such a waste to let it sit there
best regards,
ted
The emergency calls only thing is usually associated with a sim problem - like invalid sim, unactivated sim etc.
Have you paid your account?
thanks for the advise
yes i did...same thing happened, sometimes when i get signal, i cant seem to use data connection...cant even make phone calls...if im lucky i can make 1 out of 10 times..
i suspected the sim card problem, that's why i went to AT&T store for a replacement.
Solved
I had the same problem, I also have the A8183
To solve it, I went fastboot mode with USB plugged.
then on Android SDK, I did :
./fastboot-mac enableqxdm 0
./fastboot-mac oem boot
just fastboot for pc
and the phone reboot, turn it off and insert your SIM.
I knew it was fix first boot because sdcard was now mountable.
Then SIM was recognized.
But then I have USB problem in recovery, I think I'll need to flash the misc partition.

What you are describing is the fix for the usb brick issue. This is not the problem here.
To me this sounds like a faulty handset, as all the software fix options seem to have been done. I'm no expert though!
what is fastboot-mac
im using windows xp with androidsdk tools
i have fastboot command...how do i type that?

You can give the commands a go, but I doubt they will help with this. Have a look at the threads on usb brick.

Try flashing to a different compatible radio version as the version you currently have may be causing the poor reception/signal strength issues.

Hmmmm - the rooting process does not affect the A8183 - cos that's what I've got and it works fine. Maybe try and flash the Telstra ROM? That's the one that would have come with the phone in the first place. Who knows, that might reset something? Probably a long shot but you sound desperate!
You can get that ROM in the ROM sticky in this topic.
Now i have 0.80 bootloader it wont let me install the telstra rom since bootloader version being different (0.75)
any idea how i can override that?
After the rooting process when i first got the phone everything was working fine til two days ago

you could try this: http://android.modaco.com/content/h...-com/310186/mcr-telstra-8183-mod-version-3-5/
I think that will work with 0.80 bootloader.
I guess it's not easy to take the device for repair as I'm tippin you got it through eBay or similar, and HTC in the US probably won't support the warranty.
I believe that i had sort of the same issue as you are describing, sometimes my 3G connection died, and there was nothing i could do too get it back, and it sometimes failed to make a connection when i tried to make calls with full coverage.
I don't know how i got the problem, because the phone has been fine since i rooted it 1 week ago.
I decided to go back to the latest radio update I had before I rooted, and now it works fine again.
I used 32.34.00.28U_4.05.00.30_2 from the stock HTC radios thread. (new users not able to post links)
Hope this solves your issue as well, I have an unbraded Desire A8181.

im going to give the radio you mentioned a try...would u mind telling me where are you located and what network provider are you with?
Tried that radio already now it shows signal but the behaviors are the same, feels like its trying to establish connection but got stuck on upload (not sure if thats the case since only the up arrow stay lit but not the other one)
@teddyonair: did u drop down ur mobile by any chance ??? might be some hardware disconnection inside is giving u this trouble i guess.... otherwise with so many software reflashing & modding,ur mobile should have been working by now....
u better get a professional help either from the htc or from someone who deals with htc repairs.... this is my sincere advice if u wish to listen to me.... hope u have not screwed up ur mobile.... might be a hardware problem... just try this once... ok ????
i've managed to unroot the phone with telstra shipped rom. phone has been acting the same way.
so im not sure if it's the hardware issue. anybody has experience how to send the phone back to Telstra Australia for repair?
thanks!
It sounds to me like you may have a faulty antenna in your phone

[Q] Disconnected because service is unavailable

Guys I am using HTC One X and facing a very frustrating problem. My data connection disconnects after every 10-15 minutes. When I go to the settings option it says ""Disconnected because service is unavailable"".. If I tap it to make it switch off and then tap it again to turn it on, it keeps saying the same thing "Disconnected because service is unavailable". The only method to make the data connection work gain is to
a) Switch to airplane mode, and then switch it back again to normal mode, and data connection would connect
b) Change the network connection mode to WCDMA (as its not available in my region, network goes off) and then turn it back to GSM or WCDMA/GSM (and the network comes back again) and data connects automatically....
I am not the only one facing this problem.. Check out these links too.

Even if you go to google and type "HTC ONE X d" it will show the problem in suggestions too. My HTC One X is not rooted. Its running on JB and stock Sense ROM.
Can anyone help me out ??
1) I have checked other threads before creating this new thread because on other threads people are talking about rooting. I dont have a rooted and phone and I wont root it now.
2) I tried factory reset many times. It doesnt help.
3) I tried other SIM cards too. And face the same problem with other SIMs too.
4) I contacted my service provider too. APN are all correct. I dont face any problem with the same SIM and APN in my other handset (HTC Inc S)
That is very strange indeed.
Did you mess around with the kernels, as that seems to be, very often, messing with the radios.
If not then it might as well be factory error... I would recommend that you try flashing a custom rom like ARHD or if you are not on the WWE version, then you can download the newer WWE rom from the ARHD thread as well.
If that doesn't help, well then, you might wanna consider bringing it to a repair shop.

ok.. i installed a custom ROM (AOSP) and the problem disappeared. But i didnt liked the ROM so i came to Sense based ROM (ViperX) and the problem started again. So it seems that there is no problem with the phone itself. It shows this problem when running sense rom. Any help ??
Try ARHD

no signal after flashing rom

i have a samsung galaxy s3, ive been rooted for a long time and flashing roms all the time. well i flashed a rom just now and i have no signal, not sure if i burned out the radio (not sure if thats possible, but it also said to insert sim card while it was already inserted), but i dont understand how that would happen. the sim card works in another phone that im using now, so its not the sim card thats causing the issue. my carrier is at&t, and no signal showing, not data or cell (wifi still works, but thats a different story). has anyone experienced this and know how to fix it? im guessing modem flashing, but not entirely sure. can someone please point me in the right direction? Thanks in advance!

I believe you need to do a factory reset. Backup your data first!
Sent from my SGH-T999 using XDA Premium 4 mobile app
The first thing to troubleshoot you should do is flash back to a rooted stock rom and make sure the data is working there. If so this will rule out any sort of hardware problem. You didn't say whether or not you did but you can also try fully wiping the phone (dalvik/cache, system, and data), re-download the rom incase you had a bad one the first time and reflash. Other than that check that maybe check the apn settings.
Yup I ended up doing that last night..im back on the stock root injected rom. So im still rooted and network now works! So im glad. How would I flash a rom without losing the network this time?

Now that you have flashed back to stock a full wipe has been done in the process. At this point all you can do is flash it and see, but as i said i would redownload if you plan on using whatever rom it was you mentioned in the OP. I would also do a full nandroid backup to save the pain of using odin incase it doesn't work. I imagine the problem was with lingering files/fragments from multiple flashes that were causing the problem, in any case whatever the problem happened to be it was software related.
K will do. Its just weird because the md5 matched and everything..but I will for sure download the rom and gapps again. Thanks for the tips!

well, i finally got the service to work after flashing a rom. it still remains a mystery to me tho, i used to always use the illusion rom everyday, for months. i decide to flash the same exact one but no service, i download it a couple more times and still no service after flashing about 3 or 4 times. i tried a completely different rom and the service is active. i dont understand why and cant figure out what is so different this time hah. o well, im just glad its all working now even though its with a different rom. thanks for the help guys!
ok, im back =[
i was using the carbon rom with no problems, it was working great, but just a half hour ago i was listening to music and texting (i always do this), and then phone just turned off. I tried to reboot it but it wont! it always shuts off while booting. i made it to CWM, but it turns off while in CWM. i also made it to download mode, which led me to assume that the phone is not bricked, but it doesnt stay on download mode, it just turns off randomly. i figured maybe it was battery, so i tried another, and no change! does anyone know what the issue is? i cant figure out how to keep the phone ON, or why its not staying on.
btw, i got it to boot completely just once, and it was acting up still. any ideas? please help
Thanks in advance

Problem with my connectivity

Hi!
I'm currently running the DN3 ROM and I have installed the latest version of the (v5.5 with update 1).
I'm experiencing connectivity problems where my phone simply loses connectivity. Don't think it is my operator (I'm I Sweden).
I can't post in the dn3 forum (or the developer forum) so I'm asking here hoping someone can help me.
Thanks!

I have the same problem just find a good rom that can run it and check your boot loader if its up-to-date
I'm sorry I do not follow. (n00b of n00bs)
Do I have to flash a new/dirrerent ROM or the same one again?
My bootloader is N7100XXUFND3. is that up to date or an old one?
Ok I'm learning as I go here I my bootloader is N7100XXUEMK9.
Is this good or bad? ☺
Ok I'm not sure if this really helped my problem but I tried to think what I had done the day I started having the problems and the only thing I could think of that I had done was installing Adblock. So I uninstalled it and restarted my phone (for the twentieth time today) and then it worked again.
Could this have anything to do with my problem or was it just a coincidence?
Nope! Didn't help at all. Any suggestions?
Does anyone know if this is a problem with the dn3 ROM or if it just me? Haven't seen anyone else with this problem.

Hello
I have LG G3 the international version with installed stock rom 5.0,
Before I install it, I backed up the previous kitkat rom.. When I installed the lollipop stock rom I decided to go back to my previous kitkat rom. After restoring it and booted it everything was ok but it says no service, emergency calls only. And the signal at the status bar was refreshing every second automatically. I tried to return to that lollipop rom to see whether the signal is ok or no but there was no problem with it. But I dont know whats the probkem in that kitkat rom.... Plzzzz helpppp mee!!
I have the same problem! I used a custom lollipop rom and messed with something so I had to restore the stock Kitkat.
Now it keeps searching for the signal and says "no service" It found the signal for a few times but lost it immidiately.. Wifi works fine.
i would be rly thankful if somebody can fix this.

I have found a lot of threads and people reporting this issue. Bought a D855 32Gb from China that has this problem...
Phone tries to get signal a couple of seconds and then a cross.. and so on..
I tried everything I think, I passed for all the bricks the phone can do: Automatic Reboot / Boot Loop / Fast Boot / Security Error / Factory Reset Status 2 / Dead (QHSUSB_DLOAD) - I can help anyone that has any of those problems : )
In one of the flashes my phone turned to D855RE, similar case to other people, also the message "Current version is not available for user. Can't find matched cust for NT-Code mcc/mnc".
Please if anyone was able to fix the problem report here, there is a lot of people waiting for the answer 20 threads in different networks, I will post the solution in each of those. Thanks!

HI. i tried to change to several radio but I still don't have a signal. I just can't find the thread from other site, that it could be a D850 not an D855 motherboard. He tried to change the ROM to D850 and finally got a signal.

If you can, return the phone. As previous post suggested, its a popular thing from some chinese sellers to change the model. You will see the original model in your motherboard (you have to disassemble the phone) and have to flash the proper stock image. First confirm that the model is the model you ordered.

The phone was okay, this started happening when I flashed stock Marshmallow, then I flashed MIUI KitKat rom to see if its the the marshmallow that does that only, but it was on MIUI as well, after that I flashed Fulmics, but still the same. Now I'm on stock Marshmallow and it's doing it as well. I found a little "thing", when you set the network type to WCDMA/GSM there is no more no service, everything works. But when you put LTE it goes down.
If you suspect this can be the case of model tempering by seller, open your phone and unscrew the upper plastic cover, at the right you will see the Motherboard factory code with the phone model in it. Youll have to flash an according complete stock with flash tool.
